Multilayers method for designing the W-shape raised cosine few-mode fibers

Optical Spatial mode-division multiplexing that exploits the new few-mode fiber (FMF) technology is a promoted solution for the new optical communication systems. We work on the multilayers method of designing the new optical communication systems FMF. These systems suffer essentially from differential mode delay. In this article, we implement the multilayers method of designing an arbitrary fiber profiles with our own Matlab code and we proposed a fiber profile design with a full control of differential mode delay regions in the C-and L-bands, for six linearly polarized modes circulating in FMF with the cited method.
